Just a quick help on a question :)

Oh okay im having trouble with questions

Write  a balanced equation , including subscripts, for the combustion of ethanol  in a good air  supply ? okay  i dont get when its says good air supply  and i write etanol as  CH3CHOHCH2 but but the book writes it as C2H5OH(l).  So how do i write these kind of equations . that say a good air supply of e.g carbon monoxide


I would really appreciate  any help thank you

That happens to be ethanol, the thing that your book writes it as. The thing you believe to be ethanol, "CH3CHOHCH2", is actually no-clue-what *shrugs*. It has three carbons, so it cannot be ethanol. It is also missing a hydrogen (double bond?)

This?


By good supply of air, I'm assuming it undergoes complete combustion

This here would be your answer.

thank you  i think i did the semi structural formula

Semi-structural formula of what? There's a whole carbon difference between...

and i write etanol as  CH3CHOHCH2 but but the book writes it as C2H5OH(l).

wow didn't realise i wrote ethanol like that i meant CH3CH2OH
